Phase A of the 4c task brief. Survey found the integration already
exists and ships (mAi#228, 2026-05-15) — the question is which slice
deepens it next.
Plan covers:
- Otto-PWA structural notes (Go backend + Bun/TS frontend in m/mAi, not
m/otto — ADR-006 moved PWA code into mAi)
- Existing MCP-consumption pattern (Bearer-token JSON-RPC bridge,
graceful 501 degradation, 4 endpoints registered, frontend shells +
client TS, live at https://otto.msbls.de/projax/)
- 3 deepening slices: (S1) timeline surface, (S2) CalDAV writeback,
(S3) dated docs quick-add
- Recommendation: ship (S1) first — Phase 4a just landed /timeline
in projax web, the data + aggregation logic exist, exposing via MCP
is a clean wrap with no schema or auth model change
- Impl plan if greenlit: 3 slices across projax + mAi with cross-repo
deploy verification
Out of scope until head greenlights: writing any code in m/mAi.
